Be itknown that L'LomsM. Bnown a citizen of the United Statesyresiding" at Beverly, in the-county of 'Essex and State ,of Massachusetts,-hav e invented certainlms proveinents in Rebound Control for Lasting-Carriages of'which the following description, in connection with the acconipanying {drawings is a specification, like referencecharacters on the draw ngs 1nd1- eating like parts in the several figures.

Thisinventlon relates to lasting machines andisih erein' embodied in the type of bed lasters which is shown in the United; States a Letters PatentiNo. 1,018fl77 granted Feb.

there is acarriage upon which the heel lastand the-'lasting devices intooperative relation. A latch is provided -for'securing the \Vhile it occupies thisposition a heel band isclosedabout-the heelend of the shoe, this movement being effected from the camshaft through yielding connections and a lever which is fulcrumed in the carriagevVhen this latchis released, reaction ofthe spring takes effect through theleveri ,fulcrumed in may embrace without sp'ecialfadjustment, lasts of different sizesyand of actuating-the the carriage to thrust the carriage back wardly in a manner well understood by those ,familiar with this type of. commercial machine. A 'i i It will be noted that the spring referred 1 to has the double function of actuating the heelband 'yieldinglyftvhjereby said band heel carriage automatically to a position for allowing the removal ofthe shoe from the machine. particularly upon those machines employed for lasting heavy shoes, that a stiff spring is I required for obtaining the proper heel band closing pressure and that this spring reacts to move the carriage backwardly' with ob-x jectionable force causing a rebound which sometimes brlngs the. carriage forwardly the carriage.

It 1sv an object of this invention to make provision forwcontrolling the rebound of the carriage.

I i It is another feature of this invention to combine with the yielding buffer a brake dea em s: Patented'Oct.20,1914. Application filed ec mber 31, 1910; serial No. 600,272.

again in a manner to damage the shoe which 1 the carriage to check that movement and then will cooperate with the buffer to bring the carriage torest after a slight forward movement.

Theinvention is embodied in a'bufi'er rod which is yieldingly mounted in the carriage and adapted to engage a stop on the frameand a spring brake arranged to engage the bufier rod frictionally and resist its rear ward movement into contact with the stop on the frame and also resist the forward movement .of the buffer in' the rebound of The invention will now be explained in COIIHGCUOII with the accompanying drawings and will then be pointed out in the claims. i

chine of the class described equipped with 5 a this inventlon. Fig. 2 is a perspectiveview a The frame 2 ofthe machine has a track liin which theheel lasting carriage 5-is mov-z carriage is adapted to hook over an up-' standing projection on the trackas shown in Fig. to secure the carriage in its open atlve POSltlOIlQ The carriage supports a.

alever 15 that is fulcrumed, at 16 and the.

lowerend of which stands in the'path of a rocker 2O thatis pivoted to theframe at 22. j. v

The rocker is actuated from the power shaft ,25 [and so long as the latch? remains engaged With the frame the. power will beg,

transmitted through the lever 15 and the spring 14: for closing and compressing the heel band around the sides of "the heel.

Wh'enjthe latch islifted the spring contracts and turns the l'ever ;15 with its lower end against the rocker, thereby impelling the.

s5 b 011 r0118 6 and a latch 7 secured to the i I g 's The carriage is provided with eyes30 in which is guided a plunger rod 32 that has a collar 33 between which and the rear eye 30 a spring 35 is confined. A plate 36 is attached to the rear end of thetrack 4 in osi-' tion to be engaged .by the rear'end the buffer rod 32. end of the track 4 is a curved spring 40 the free end of which is bowed forwardly and downwardly to present a resilient neck 41 1 and a buffer engaging portion 42, the front end of the spring being upturned. In the use of the devices, the buffer rod 32 first meets the portion 42 of the spring which acts substantially to retard the backward movement of the buffer and in the mean time the momentum of the rearwardly moving carriage is taken up by the spring 35. The

engagement of the rod 32 with the spring 40 v upon the rod 40 tends to carry the engaging portion 42'of the spring backwardly bending the neck 41 and the curvature or formatlon of the spring is such that in thisbending of the neck the engaging portion 42 is pressed downwardly w1th increasing force upon the rod 32. Any

formation of the spring which will reduce against the front'eye 30 to press the heelcarriage forwardly also the bent neck of the spring 40 reacts to press forwardly The re-action of these two springs is or maybe enough to move the heel carriage forwardly to an extent that will free the rod 32 from the spring 40 or will nearlyrfree it sothat there is little or no resistance for the operator to overcome when he again draws the heel carriage forwardly into operative position.

The rod 32 may have a depression 31 in that portion of its face which is engaged by the portion 42 of the spring 40. As herein shown thisis formed as a tapering depression by a longitudinal concavity in the face of the rod.

Preferably the rear end of the rod will be higher than the main portion of the rod and will thereby form a projection by which the rod will hang on to the spring 40 and prevent the heel carriage from moving forwardly far enough to free it entirely from the spring The spring 40 may be provided Also attached to the rear with slots 46 to-permit vertical adjustment for regulating its action upon the rod 32.

Having explained the nature of thisinf ventlon and described a preferred construction embodying the same,I claim as new and desire to secure by Letters Patent of the United States: a v 7 1. A lasting machine having, in combination, a heel lasting carriage, a track over which the carriage is moved away fromlastwhich the carriage is moved away from lasting position, the rod 30 yieldingly mounted by the spring 35 in the carriage, and the spring 40 having the portion 42 arranged to engage the rod frictionally and the neck 41 formed to be compressed by the backward movement of the rod andto" co operate withthe spring 35 in moving the carriage forwardly jagain.

3. A lasting machine having, in -combina-' tion, a heel lasting carriage, a track'over which the carriage is movedaway from lasting position, the rod 32 having a depressed face 31 and a relatively enlarged rear end, and the spring 40 arrangedto ride over the rod end and engage in the depression and then be compressed, and thereafter to hang on to the rod end to retard rebound of the carriage. 1 a

4. A lasting machine having, in combination, a heel lasting carriage, a track over which the carriage is moved away from lasting position, and a spring having a straight oortion 40 attached to an upright face of the track and extending upwardly and then forwardly at 41 and having a portion 42 bent downwardly and forwardly away from said straight portion and arranged for its lower face to be frictionally engaged by a portion of the carriage, the spring being free to yield bachwardly while also acting as a drag on the carriage. Y In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
